To all 'whom z't may concern:

Be it known that I, NELSON B; HENRY, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Apparatus for Grinning Cotton, of which the following is a specification.` i My invention has relation to an improved apparatus for ginning Vcotton and in such connection it relates more particularly to the arrangement of parts whereby the ginning operation is accelerated and more perfectly carried on.

Heretofore in the ginning of cotton, the raw `material was delivered to a feeder and fed therefrom to what is known as a roll box. A saw cylinder in revolving traverses this box and pulls or snags the cotton fiber from the roll and draws it through the seedseparating ribs. The'ibers so conveyed by the saw cylinder is removed from the teeth of the saws either by a brush or by an air blast and delivered to a lint flue. Where the cotton is full of hulls a huller gin is employed in which the raw material is delivered to a hulling mechanism rather than to a roll box. This huller mechanism comprises a picker roll and huller ribs co-acting with'the saw cylinder7 the huller ribs permitting the cotton 'and seed to be drawn by the saws into the roll box and to the seeding ribs,

the hulls only being caught by said huller ribs.

huller gin, the ginning Operation has here# tofore been comparatlvely slow and relatively imperfect in that it was impossible with a single roll box to present the raw material to the gin saws in such relative compactness andwith such speed as to perv mit the ginto be run at a speed which would secure the maximum output with the mini- Thus if the cotton were fed too rapidly or rather with such rapidity as the revolving sawV cylinder wouldtheoretically require, the roll box would become Y choked up and the gin would not operate l advantageously.l If however the speed of the feeding of the raw `material to the roll box was reduced, the lsaw cylinders did not take 'off the ber to their fullest capacity and the output of the gin was therefore decreased. Again if the roll in roll box was of a density less than that theoretically re Whether the gin be` an ordinary gin, or a tively compact rolltoa second saw cylinder i which effectually removes the valuable bers from the seed escaping from the rst ginning operation. I thus secure the maximum of speed at which the cotton can be passed through the gin and also secure the extract-ion of a maximum amount of the ber with- Vout an appreciable increase in power to run the gin and with but a slight increase in the initial cost of construction of the gin. I also secure by my invention great economy of space in that a single gin of my present construction will fill the requirementsof what now is filled by a stand of three or four gins.

` To redesign or reconstruct the gin so that it maybe capable of carrying' out successfully this double ginning of the cotton requires certain changes in form and location of the parts and requires also the provision of means whereby should the lower or second roll box become choked up or the roll therein become too dense for proper maniplulation, the feeding of the raw material to the first roll box may be automatically regulated. These necessary changes in form and y vlocation and the means forv automatically governing the feed of the raw cotton to the gin by the condition of the second roll box constitute my present invention.

The nature and scope of my invention will be more fully understood from the following description taken in connection with the Vaccompanying drawings forming part hereof, in which- Figure 1 is a vertical sectional View of a gin embodying the main features of my invention, Y

lig. 2 is a side elevational vie'w thereof, an

Fig. 3 is a perspective view of the shoe or guard form' g part of thev feed regulating mechanism.

In the drawings I have illustrated for example a hullergin in which the ber or lint 55 of the seed ribs.

in a gin of any known type whether the same l l have the huller mechanism or notY and whether an air blast or abrush be the prelled Ineans for removing the lint from the' saws.

Referring to the drawings 1-1 represent the feeding rollers coperatng in a hopper ..2 with a picker rollf3 to Yproperly feed the raw material to -achute 4. The picker roll is designed to carry the cotton over a screen breast 5 whereby the dirt or trashv loosened from the cotton duringits travel through hopper 2 mayv escape to the dirt and trash conveyer 6.

The chute 4 in case of a huller gin is pivoted as at7 so that it vmay discharge the raw material selectively to the `upper roll box .-8 orto the huller chamber 9 and .thence to the picker roll 1f() coperating with the. :hullerv ribs 11 .in the presentation of the ber: separated from `the hulls to the saws 215 1of the upper saw cylinder 12. This cylin yder traverses the lower end of theroll box '8 4and 1coperateswith the seeding ribs 13. `The cotton adhering to the .teeth of the saws is `blown by an air blast delivered from noz- Zle Y1 4ginto a lint-flue 15. f

The roll box .8 has at its discharge-.or

throat a. notched bar or lambrequin 16 lpro-f jecting from the side of the roll box .to-

ward the saws. In the usual construction and arrangement of such bar 16,*the prongs .orringers project into the spaces between theV saws of the saw cylinder .and thus serve to more V,or less obstruct the discharge from ythe -roll .boxand insure 'the formation of a tight 40 or relatively dense roll for presentation to the saws. Inasmuch as it isessential in my improved lgin to present the cotton and seed l to the lsaws 412 in a relatively ytenuous roll, the Ynotched .bar 16 'is considerably. shortened in width so that its flanges or prongs do not enter Ythe space between the saws vbut stopsome distance in front of the periphery V.of the .saw cylinder. This construction vand arrangement permits of the rapid but somewhat incomplete separation of the ycotton liber from the seeds, some portionfof the l Vfiber remaining on'the` seeds Aas they pass ldownwardthrough .the passageway or .outlet i1'7 below .the saw lcylinder and ,at .the bottom Below this passageway 17 is arranged a second .roll :box 18 .to Vreceive Vthe seed with l,adhering fiber fas it escapes v from the upper roll box 8. Thisiower roll "xbox 18'has `at itsnzlcwer end i or .throat a notched bar or lambrequin 19 the prongs f or iingersof which y.extend into thei spaces betaveen'. :the J saws of the lower or second saw cylinder 20, to insure, in y.the roll .box

18, Vthe formation lof atrelativelfy ktight orv .dense roll, `VVithinthe rollibox 18 i-'evo'lves a float 21 which serves Vto revolve the relatively heavy bodyor roll of seed within the 100x155. l

VWhere, as illustrated, the gin embodying my invention is a huller gin, there is provided a second or lower huller chamber 22 with picker roll 23 and huller ribs 24. The upper huller chamber 9 is arranged to discharge itshulls with adhering fiber into the lower huller chamber 22 in which the picker 75 roll 23 coperateswithjthe rbs-l24 in performing anotherhulling operation.'

The residue from roll boxV 8 aftergthe material `i-n va loose rol-lhas been subjell t0 SL ginning operation isv next presented to the gin .saws 20 in relativelycompact and dense roll. luthis step. the fiber .clinging to the saw teeth of cylinder 2O maybe removed by an `.air blast from Vnozzle .25 andV discharged into a lint flue 26,. In practice both lint iiues 15 and 26'discharge preferably into a common fiue not shown.

"llo insure the vproper v,operation .of the gin at maximum speed and with v-the economic removal of the herQa-nd without human supervision there is provided a means. where-y bythe degree of compactnessof the rollin the .lower roll box automatically regulates Vthe feedk of raw material through the' feed Y-rollers into the upperor loose rollbox 8. 95

While such a meansis illustrated in .lts preerred form in the .drawingsyitis `tobeunderstood that changes ormodifications of this form without change kin function lci the means will Vlie withinV the `purview 0f my in'- vention.
